Lentigines

Lentigines, also known as liver spots or age spots, are flat, brownish spots that commonly appear on the skin as people age. They are caused by the accumulation of pigment in the skin and are more common in people with fair skin, red or blonde hair, and blue or green eyes. Lentigines are benign (non-cancerous) and are not contagious.

Lentigines are most commonly found on the face, hands, and arms, and are more common in people who have had prolonged exposure to UV radiation, such as those who spend a lot of time in the sun or use tanning beds. Lentigines may also be caused by certain medical conditions, such as Addison's disease or Peutz-Jeghers syndrome, or by the use of certain medications, such as corticosteroids.

Symptoms of lentigines may include the presence of flat, brownish spots on the skin that are typically larger than freckles. The spots may be single or multiple and may range in size from small to large. Lentigines may cause no symptoms at all, or they may be accompanied by itching or a burning sensation.

Treatment for lentigines is generally not necessary, as the spots are benign and do not cause any harm. However, some people may choose to have lentigines removed for cosmetic reasons. Treatment may involve the use of over-the-counter or prescription bleaching agents, or laser or light therapy.

In addition to treatment, there are several steps you can take to help reduce your risk of developing lentigines:

  • Avoid prolonged sun exposure, especially between the hours of 10 a.m. and 4 p.m. when the sun is strongest

  • Wear protective clothing, such as a wide-brimmed hat and sunglasses, when you are outdoors

  • Use a broad-spectrum sunscreen with an SPF of 30 or higher on a daily basis, even on cloudy days

  • Avoid using tanning beds

By following these precautions and seeking treatment as needed, you can help to manage lentigines and reduce your risk of developing this type of skin condition. If you are concerned about lentigines or have any other changes in your skin, it is important to see a healthcare provider for evaluation and treatment. 

It is important to remember that lentigines are a normal part of aging and are not a cause for concern in most cases. However, if you have a sudden or unusual change in your skin, or if you have any other concerns, it is important to see a healthcare provider for evaluation and treatment.
